## Abstract

A method and system for adapting the voltage supplied by a high performance electrochemical storage device provide for: supplying a voltage for a load using a high-performance electrochemical storage device; monitoring the temperature of the high-performance electrochemical storage device; an adapting the voltage supplied by the high-performance electrochemical storage device as a function of a change in the monitored temperature thereof in a way that counters a change in the value of the power density of the high-performance electrochemical storage device attributable to the temperature change.

## Claims

### Claim at position 1

1-9. (canceled)

### Claim 10

A method for adapting a voltage supplied by a high performance electrochemical storage device, the method comprising:
supplying a voltage to a load using a high-performance electrochemical storage device;
monitoring a temperature of the high-performance electrochemical storage device; and
adapting the voltage supplied by the high-performance electrochemical storage device as a function of a change in the monitored temperature in a way that counters a change in a value of a power density of the high-performance electrochemical storage device attributable to the temperature change.

### Claim 11 (depends on 10)

The method of claim 10, wherein the adapting is performed such that the power density of the high-performance electrochemical storage device remains constant while the voltage is supplied.

### Claim 12 (depends on 11)

The method of claim 11, further comprising calculating a power of the constant power density of the high performance electrochemical storage device using a formula P=U2/4Ri, wherein Ri is an internal resistance of the high-performance electrochemical storage device and U is the voltage provided in this supplying step.

### Claim 13 (depends on 10)

The method of claim 10, wherein the high-performance electrochemical storage device is a supercapacitor.

### Claim 14

A system for operating a load, the system comprising:
a high-performance electrochemical storage device that includes at least one output for an electrically conductive connection to the load;
at least one sensor configured to measure a temperature of the high-performance electrochemical storage device and the voltage at the at least one output; and
a system management unit that is connected to the at least one sensor, wherein the system management unit is configured to alter the voltage at the at least one output as a function of a change in the temperature of the high-performance electrochemical storage device in a way that counters a change in a value of a power density of the high-performance electrochemical storage device attributable to the temperature change.

### Claim 15 (depends on 14)

The system of claim 14, wherein the system management unit is configured to adapt the voltage at the at least one output in such a way that the power density remains constant while the voltage is supplied.

### Claim 16 (depends on 14)

The system of claim 14, wherein the system management unit is configured to measure voltage dropping across the load when the load is connected to the at least one output.

### Claim 17 (depends on 14)

The system of claim 14, further comprising a power and control unit, wherein the power and control unit is configured to alter a current that the high-performance electrochemical storage device supplies to the at least one output.

### Claim 18 (depends on 14)

The system of claim 14, further comprising a power and control unit, wherein the power and control unit is configured to alter a current that the high-performance electrochemical storage device supplies to the at least one output to correspond to an instantaneously required current of the load while the load is electroconductively connected to the at least one output.
